Messier 23, also known as NGC 6494, is an open cluster of stars in the northwest of the southern constellation of Sagittarius. It was discovered by Charles Messier in 1764. It can be found in good conditions with binoculars or a modestly sized telescope. It is in front of "an extensive gas and dust network", which there may be no inter-association. It is within 5° the sun's position so can be occulted by the moon.

NGC 2539 is an open cluster in the constellation Puppis, located at the north edge of the constellation. It was discovered by William Herschel on January 31, 1785. It is a moderately rich cluster and with little central concentration, with Trumpler class II1m.

<span class="mw-page-title-main">NGC 5084</span> Galaxy in the constellation Virgo

NGC 5084 is a lenticular galaxy in the constellation of Virgo. It is located at a distance of about 80 million light years from Earth, which, given its apparent dimensions, means that NGC 5084 is at least 200,000 light years across. It is one of the largest and most massive galaxies in the Virgo Supercluster. William Herschel discovered it on March 10, 1785. It is a member of the NGC 5084 Group of galaxies, which is a member of the Virgo II Groups, a series of galaxies and galaxy clusters strung out from the southern edge of the Virgo Supercluster. The galaxy is seen nearly edge-on, with inclination 86°, and features a warped disk and large quantities of HI gas extending along the disk, probably accumulated after multiple accretions of smaller galaxies.

NGC 1381 is a lenticular galaxy located in the constellation Fornax. It is located at a distance of about 60 million light years from Earth, which, given its apparent dimensions, means that NGC 1381 is about 55,000 light years across. It is a member of the Fornax Cluster. NGC 1381 appears edge-on and features a thin disk with high surface brightness and a boxy bulge. Both the box-shaped bulge and the kinematics of the central area of the galaxy suggest that NGC 1381 has a bar.
